PHYSIOLOGICAL BENEFITS OF MICROBIAL MN OXIDATION

该子项目是利用 由NIH/NCRR资助的中心赠款提供的资源。子项目和 研究者（PI）可能从另一个NIH来源获得主要资金， 因此可以在其他CRISP条目中表示。列出的机构是 中心，不一定是研究者的机构。 锰氧化物在金属和有机物的循环中发挥着重要作用，细菌介导的锰氧化主要是这些反应性锰氧化物的来源。许多不同的系统发育和生理类型的细菌已被证明氧化锰，但这些氧化物在细菌生理学中发挥的作用或益处尚未确定。我们正在研究锰氧化物对紫外线、干燥、机械破碎和噬菌体感染的保护作用。我们想通过TEM显示细菌产生的锰氧化物物理包覆细胞。

This subproject is one of many research subprojects utilizing the resources provided by a Center grant funded by NIH/NCRR. The subproject and investigator (PI) may have received primary funding from another NIH source, and thus could be represented in other CRISP entries. The institution listed is for the Center, which is not necessarily the institution for the investigator. Mn oxides play an important role in the cycling of metals and organics, and bacterially mediated Mn oxidation is largely the source of these reactive Mn oxides. Many different phylogenetic and physiological types of bacteria have been demonstrated to oxidize Mn, yet the benefit or role these oxides play in bacterial physiology has not been determined. We are investigating the protective effects of Mn oxides to UV light, dessication, mechanical disruption, and phage infection. We would like to show that the Mn oxides produced by the bacteria physically coat the cell by TEM.
